Your guide to Design-Build
A More Energy-Efficient Home
by Marc Brahaney, October 15th 2025
Is your home losing energy? Here’s how to fix it and potentially upgrade the look and feel simultaneously. As a homeowner, you work hard to keep your home comfortable, cozy, and cost-effective. But if you’ve noticed drafty rooms, chilly spots near windows, or higher-than-usual heating bills, your house could be losing energy in other ways as well.
A home energy audit may be the first step in the right direction to uncover where your home is underperforming. While you can hire a professional for a full evaluation, many homeowners start with a simple walkthrough to spot areas that need attention.
Once you’ve identified the problem areas, it’s not just about sealing leaks or replacing weather stripping—it’s about thinking long-term: How can I upgrade my home to make it more efficient, comfortable, and valuable?
Let’s talk about your renovation opportunities:
Poor or missing insulation is one of the biggest reasons for heat loss—especially in older homes. If your attic, walls, or floors feel cold in winter or hot in summer, it may be time to:
- Add or replace attic insulation.
- Insulate exterior walls (especially if your home was built before the 1980s).
- Install insulation under floors or in crawl spaces.
The bonus is that good insulation keeps your home cooler in summer, too.
Replacing outdated windows and doors provides an opportunity to create a more comfortable interior and improve your home’s curb appeal. Swapping them out for energy-efficient models is one of the most impactful renovations you can make.
Look for the specifications we demand in all new windows: double or triple-panes, low-E coatings that reduce heat loss, insulated exterior doors with secure weather stripping.

Replacing outdated windows and doors provides an opportunity to create a more comfortable interior. Swapping them out for energy-efficient models is one of the most impactful renovations you can make.
Sealing and insulating ductwork can improve your home’s efficiency. If you have a forced-air heating system, the ductwork could be leaking warm air into areas you don’t even use—like basements or crawl spaces.
Sealing and insulating your ducts reduces wasted heat, makes your system run more efficiently, and keeps all rooms at a consistent temperature.
Upgrading your appliances impacts your energy bill and quality of life, including heating systems, water heaters, and even your washer and dryer. If your appliances are over 10–15 years old, replacing them with ENERGY STAR® certified models can make a big difference.
Some key upgrades to consider are a high-efficiency furnace or boiler, a tankless water heater, a heat pump system (for both heating and cooling), and smart thermostats for better control.
Another step you can take, maximize natural light and passive heating. During your upgrades, think beyond insulation. Small design changes—like enlarging south-facing windows or using lighter interior paint colors—can improve natural light and passive heating, reducing your need for artificial lighting and heat. When we design and renovate older homes, we place an emphasis on larger windows and more natural light; it’s good not only for your heating bill but your health and wellness too.
You don’t have to tackle everything at once. Start with the areas where you feel discomfort or see signs of energy loss, and work toward upgrades that add value, comfort, and sustainability to your home.
Whether it’s replacing drafty windows, boosting your insulation, or investing in efficient appliances, these smart renovations will help you enjoy a more comfortable home and lower monthly bills—all while increasing your home’s value.
